[BUG] Python: Restart Language Server command fails to start the language server after shutdown #24218
Description
Type: Bug
Behaviour
I'm in a multi-root workspace. I use the command palette to run Python: Restart Language Server its failing to re-index my workspace. It fails to start up the language server again. Perhaps due to a failure to merge config values from my code-workspace file into its runtime config?
Steps to reproduce:
- Open the command palette
- Run
Python: Restart Language Server
